Advice needed πŸ’”πŸ’” ~its kinda long

okay y'all. so I don't have anyone I can go to about this, but I need some help, guidance, advice, just something. I think my husband has become an alcoholic. And he has been lieing to me about smoking cigarettes ( which may not seem like a big deal, but it's the fact that he LIED about it.) he won't talk to me about anything. I don't know what to do. I have been praying about it. It's like some days we have a good day, and we usually end up having sex. So the more I think about it I feel like he's just being sweet and open so we can have sex. And other days are just bad. We don't hardly talk, and it's just sad. We went out earlier tonight with some friends for a birthday dinner for one of them Afterwards whole we went to their house and we're hanging out. He was drinking and having a good time. Well I was trying to be flirty, I told him we could go home, clean up, and have some fun πŸ˜πŸ˜πŸ˜‰πŸ˜ if you know what mean. He said he was too tired

TOO TIRED!?! So I just replied, K, but you aren't too tired to hang out and drink? he said that it didn't take effort. He isn't the man j married anymore

I just don't know what to do, I feel like our marriage is being torn to shreds slowly and surely.
